Sadly I don't think there's any buyers out there, Tom, much as just one of these would be a lot more interesting than ~oh, I dunno~ yet another P-51D?
Interesting once you start looking...
http://en.wikipedia.org/wiki/Beriev_Be-6The engines are Shvetsov_ASh-73 type, and interestingly this is one that wasn't re-engined to turboprop power.
Quote:
The Shvetsov ASh-73 ultimately began in 1938 from a specification for a 18-cylinder, twin-row, development of the Shvetsov M-25, a license-built 9-cylinder, air-cooled, radial Wright R-1820-F3 Cyclone engine. Development continued through a series of less than successful engines, before culminating in the ASh-73. Contrary to popular belief the ASh-73 wasn't a reverse engineered copy of the Wright R-3350: "There was no need to copy the Wright R-3350-23A; the engine that was put into production was the indigenous ASh-73TK - a further development of the M-71 and M-72, which differed in being fitted with twin TK-19 turbosuperchargers (TK = toorbokompressor)." [1] rather the ASh-73 was the product of a similar specification. Since the earlier M-25 engines were a licensed copy of the Wright R-1820, there were similarities and some parts were interchangeable between the R-3350 and the ASh-73. The two engines evolved from a common ancestor and to a similar requirement.

was used on the Tu-4, the Russian copy of the B-29, but was
not a copy of the R-3350, which is interesting. I don't know if we have any prop experts here, but it's intriguing that as well as the cowls the props are B-29 'style', implying they are Tu-4 developed (copy) units. However, would an independent design come up with that kind of prop for this job?
Another byway...
